You can use the Network Solutions (A Web.com Company) Expired Domain Name Search to see if there are any expired, or soon to expire, domains that you want to try to snatch up and squat. Because, you know, everyone loves a domain name squatter.
Actually, no one loves a domain squatter except maybe his mother. Domain name squatters are turds. People who snatch up other people's domain names, and ransom them back, are turds. But, hey, you know, Free Market Capitalism, and all that crap.
